CONNECTING DEVICE BETWEEN LAMP SOCKETS AND HEATING ELEMENTS Original Filed Oct. 12, 1929 Patented July 17, 1934 UNITED STATES PATENT OFFICE CONNECTING DEVICE BETWEEN LAllIP Application October 12, 1929, Serial No. 399,147 Renewed November 29, 1933 3 Claims. (01. 219-32) My invention relates to a connecting device between a lampsocket connected to a source of electricity, and a heating device having an independent connection to the same source. The connecting device is so constructed that it performs a double purpose.

In the accompanying drawing Fig. 1 is an elevation of a connecting device between a lamp socket and a cigar lighter; and

Fig. 2 is a bottom view of the cigar lighter.

The lamp socket 10 has connected thereto a plug 11 adapted to be screwed into a socket having a permanent connection to a source of electricity. The socket 10 is provided with a pull cord in the form of a chain 12 for lighting and extinguishing a lamp held in said socket. The construction of these parts is well known and needs no description.

In the upper part of the socket 10 is an opening at 13 thru which passes a cord 14, consisting of an ordinary pair of electric conductors. These conductors are bridged upon the conductors in the socket which convey current to a lamp in the socket. There is nothing special or peculiar about connecting the conductors of cord 14 to the conductors inside of the socket 10.

At the lower end of the cord 14 is a handle 15, preferably made of some insulating material. The handle 15 is hollow and has therein an electric heating element, the edge of the container for which is shown at 16 in Fig. 2. The actual heating element is located close to, or in contact with, a perforated piece of mica 17 situated a short distance within the bell-shaped mouth of the handle 15.

As the present invention is not concerned with the details of how the heating element is constructed, such construction is not here described. Any electric heating element which will furnish heat enough to light a cigar will serve the purpose.

The heating element in the handle 15 is not normally in electrical connection with the circuit of the cord 14, but there is a. push button 18 carried on the side of the handle so that the circuit may be completed whenever desired.

As so far described, the chain 12 may be pulled to light or extinguish a lamp supported in the socket 10 without affecting the heating element in the handle 15. And the button 18 may be pushed to connect the heating element to the source of electricity or be released to disconnect it therefrom without affecting the operation of a lamp in socket 10.

The lower end of the chain 12 is connected mechanically by a ferrule 19 to an intermediate point of the cord 14. This connection is so located that there is a slack in the cord between points 13 and 19. As so constructed, a pull upon the handle will operate thru the chain and a part of the cord to light or extinguish a lamp held in the socket 10, and will do so without putting any strain on the cord where it enters the socket at 13.

What I claim is:

1. The combination with a lamp socket and a lighter heating element having independent electrical connections to a common source of electricity, of means by which a pull upon the electric conductor for the heating element will operate the electrical connections for a lamp in the socket and additional means in the conductor for controlling operation of the lighter independently of the first named means.

2. The combination with a lamp socket and a heating element, of a pull cord for lighting and extinguishing a lamp held in said socket, an electric conductor extending from the electric connection for a lamp in the socket to the electric connection at the heating element, and a circuit closer for the heating element independent of the lamp circuit, said pull cord being mechanically connected to an intermediate part of said electric conductor so as to leave a slack in the conductor between the mechanical connection and the electrical connection in the socket whereby the pull cord may be operated by pulling upon the conductor leading to the heating element.

3. A combined cigar-lighter and pull-cord for an electric lamp or the like, comprising a cigarlighter body having a heating element and a switch for closing a circuit leading to the heating element; a cable connected to the cigar-lighter and supplying current thereto through the said switch at one end; an electric light socket to which the other end of the cable is attached, said socket having a pull-chain switch controlling current flowing to a lamp therein but not affecting the current flowing through the cable to the cigarlighter; and means connecting the pull-chain of the socket to the cable.
